Data Warehousing: Step by Step
Purpose
To build a data warehouse, you have to execute certain process steps.
Process Flow
1. Data modeling
○ Creating InfoObjects: Characteristics
○ Creating InfoObjects: Key Figures
○ Creating DataStore objects
○ And/or creating InfoCubes
○ And/or creating InfoSets
○ And/or creating MultiProviders
○ Or creating VirtualProviders
2. Metadata and Document Management
○ Installing BI Content
○ Creating documents
3. Setting up the source system:
○ Creating SAP source systems
○ And/or creating external systems
○ And/or creating file systems
4. Defining extraction:

○ Or for transferring data with UD Connect: Creating a DataSource for UD Connect
○ Or for transferring data with DB Connect: Creating a DataSource for DB Connect
○ Or for files: Creating DataSources for File Source Systems
○ Or for transferring data from non-SAP systems
○ Creating InfoPackages
5. Defining transformations:
○ Creating transformations
6. Defining data distribution:
○ Using the data mart interface
○ Creating open hub destinations
7. Defining the data flow:
○ Creating data transfer processes
○ Creating process chains
8. Scheduling and monitoring:
○ Checking process chain runs
○ Monitor for extraction processes and data transfer processes
9. Performance optimization:

○ Or using the BIA index maintenance wizard
10. Information lifecycle management:
○ Creating data archiving processes
11. User management:
○ Setting up standard authorizations
